We have found the Bio-Sparge to be reliable, user friendly, effective and with a great back up service provided by Bodo Limited. It is used for the Royal Norfolk Show where there are approximately 800 to 1000 vehicle movements on the gates. We have two Bio-Sparges one is position on the sheep entrance and the other on the cattle, goat and pigs entrance. When looking at other solutions we found the Bio-Sparge to be the most simplistic and effective product on the market. We also like the fact that it is portable and can be moved easily to other entrances we have at the show.
